Yeah, the expo seminar mic situation is kind of crappy. I'd rather see at least the main people on stage have a lavalier mic so there's not all the running back and forth. You can get an 8 channel wireless system with 8 lavalier mics and 8 headset mics for like $400.
And a shared audience mic in a pandemic is a very bad idea. I was cringing watching people pass around the same mic and put it right on their unmasked mouth to speak. Someone's getting sick from that or taking it home asymptomatically to someone else.
The only real thing of note mentioned was that everyone on stage were currently working on ONE game together. Likely whatever is after Toy Story, because I can't imagine Toy Story hasn't been finished for a while.
